NCT02137187

Brief Summary

There is evidence of superiority of AV junction ablation strategy over pharmacological therapy only for symptoms of atrial fibrillation, but not for heart failure, hospitalization, morbidity and mortality. Hypothesis of trial is that AV junction ablation is superior to pharmacological therapy as regard hospitalization and mortality

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • To be eligible, each patient must be in the following condition:
  • Permanent atrial fibrillation (\>6 months) which has been considered unsuitable for ablation or failed ablation
  • Narrow QRS ≤ 110 ms
  • Severely symptomatic (atrial fibrillation-related symptoms), refractory to drug therapy for rate control
  • At least one hospitalization related to atrial fibrillation and/or heart failure in the previous year (see definition below)

You may not qualify if:

  • New York Heart Association (NYHA) class IV and systolic blood pressure \<80 mmHg despite optimized therapy;
  • severe concomitant non-cardiac disease;
  • need for surgical intervention;
  • myocardial infarction within the previous 3 months;
  • previous implanted devices (PM/ICD/CRT)
